Well, it could be a story where Naruto and Hinata are training together in a secluded forest area. As they train, they accidentally use a jutsu that causes them to be trapped in a sort of dream - like state where their deepest desires are exposed. They see how much they love each other and start making out. Another plot could be that they are both injured during a fight against a powerful enemy. As they recover in the hospital, sharing a room, they have a tender moment that leads to them making out, as they realize how close they came to losing each other.
One idea could be that Hinata starts spending a lot of time with another male character, like Kiba. She goes on training missions with him and Naruto sees them together often. Naruto starts to feel jealous because he realizes he has deeper feelings for Hinata than he thought. Another plot could be Hinata getting a lot of attention from a visiting ninja from another village. She is polite and friendly to him, and Naruto can't stand seeing them interact so closely.
One plot idea could be Boruto getting lost in a mysterious forest during a training exercise. Naruto and Hinata then team up to find him. Along the way, they face some old enemies or new threats that test their skills and their relationship as a couple. Another idea is that Boruto discovers a hidden power within himself that Naruto doesn't understand, and Hinata has to be the one to bridge the gap between father and son by helping Naruto understand Boruto's new ability.
Another plot could involve Naruto and Hinata dealing with a new threat to the village that specifically targets their family. They must protect their children and the village while also maintaining their relationship. This could include Hinata using her Byakugan in new and creative ways to help Naruto in his leadership role.
One plot idea could be a training mission where Naruto, Hinata, and Tenten are paired together. They face a powerful enemy that forces Hinata to overcome her shyness and use her Byakugan more effectively. Tenten could show off her weapon skills, and Naruto, of course, his ninja way and new jutsu. Another idea is a love triangle situation where Hinata has feelings for Naruto, but Tenten also starts to develop a crush on him, creating some tense and emotional moments among the three.
One plot idea could be Naruto and Hinata going on a mission together in a new, mysterious land. They face challenges that test their skills and also their relationship. Another could be a story set in an alternate universe where Naruto isn't the jinchuriki and he and Hinata have a more normal, but still exciting, relationship as they try to prove themselves in the ninja world.
One idea could be that Naruto and Hinata work in the same modern - day office. Naruto is the overly enthusiastic new guy always trying to prove himself, while Hinata is the quiet but highly skilled co - worker. Their relationship could start with Hinata secretly admiring Naruto from afar at work, and Naruto gradually noticing her kindness and intelligence.
Well, perhaps they are sent to spy on a powerful and mysterious clan. Naruto's rasengan ability might come in handy if they are discovered, while Hinata can use her Gentle Fist techniques to defend and also gather intel. They could start to uncover a dark secret about the clan that has implications for the entire ninja world. Maybe the clan is trying to revive an ancient and dangerous jutsu, and Naruto and Hinata need to stop them.
One idea could be a story where Naruto and Hinata go on a picnic in a hidden meadow. They could share their favorite foods and Naruto could tell Hinata all about his latest missions in great detail. Another could be them having a date at a local festival, trying different games and winning prizes for each other.
One plot idea could be exploring their family life after getting married. Maybe showing how they raise their kids and deal with the daily challenges in Konoha. Another could be a time - travel plot where Hinata goes back in time and has to change some events to ensure Naruto's success. Or perhaps a story where they go on a special mission together that tests their relationship in new ways.
One idea could be a story that focuses on their wedding preparations. It could show how Naruto is clueless about most of the traditional wedding stuff in the Hyuga clan, and Hinata has to patiently explain it to him. Another plot could be set after their marriage, where they face challenges in balancing their ninja duties and family life. For example, a mission comes up that might take Naruto away for a long time right after their honeymoon, and they have to figure out how to deal with it as a newlywed couple.
